Specification of: Letters Patent.

Patented Jan. 23,1912.

Application filed August 26, 1911. Serial No. 646,224.

To all whom it may concern:

Be it known that I, JAMES :D. BOYD, a'citizen of the United States, and residing at Arrochar, in the county of. Richmond and State of New York, have invented certain new and useful Improvements in Egg- Hatching Incubators, of which the following is a specification, such as will enable those skilled in the art to whichit 'apper-y tains to make and use the same. 7

This invention relates to incubators used for hatching eggs, and the object thereofis to provide an incubator of this class with improved means for supporting and-turning the eggs during the process of hatching the same.

It is a well known fact that in the process of hatching eggs they must be turned regularly and the object of this invention is to provide a mechanical device for this purpose which may be operated without opening the incubator if desired, and by means of which the eggs may be exactly turned to any desired extent and as often as necessary,and which Wlll serve as an egg holder, andwhich may be inserted into the frame or casing of the incubator in the manner ota tray. V

The invention is fully disclosed inthe following specification of which the accompanying drawing forms a part, in which the separate parts of my invention are designated by suitable reference characters in each of the views, and in which Figure 1 is a sectional side view of an incubator of the class specified provided with my improvement, and; Fig. 2 a sectional plan view on the line 2-2 of Fig. 1.

In the drawing forming part of this specification I have shown an ordinary incubator frame or casing comprising a top body or a casing member a supported by legs a and one side, the side a as shown in Fig. 2 is formed into a door which is hingedat the bottom-as shown at a, and the body or 'casing of the incubator is provided at one end with a bracket 7) for supporting a lamp Z)? by which the incubator body or casing is heated in the usual or any preferred manner, but it will be understood that my invention has nothing to do with the means for heating the incubator.

In the practice of my invention I provide an endless sheet or belt c-composed of wire mesh and mounted on two rollers d and (Z provided at th e ends of the body or casing of the incubator-and on the oppositesides thereofwith supports 0Z into which the ends of the rollers (Z and (Z or the trunnions with which said rollers are provided may be dropped. a

The supports d? in the construction shown, are formed on, or connected with a frame (Z which with'the endless'sheet or belt c-mounted thereon, isadapted to'be inserted into the casing'of the incubator and-removed therefrom in the manner of a tray.'

VMounted centrally of and transversely of the frame (Z is a third roller 6 which serves as a support for the endless sheet or belt 0 which constitutes the egg holder and turner proper, and in practice, the door a is provided' with apertures f through which are passed pins 9 adapted to enter axially formed recesses in the corresponding ends of the rollers (Z andd and these plns are provided with handles 9 and the inner end portions thereof are preferably made angular" in cross section as are also the said re-- cesses, 1n. the rollers (Z and (Z and when thls device is inserted into the incubatonthe .door a maybe closed and the pins 9 may be inserted into either ofthe 1'ollers*d-d and said rollers may be turned so as toturn the endless sheet or belt 0 in the required direction. i

In practice, the eggs h, a number of which are shown in Fig. 1, and three of'which are shown in Fig. 2, maybe placed between the top and bottom'parts of the endless sheet or belt 0 and the diameter of the rollers cland f J (Z is such that the said eggs willapproximately fill the space formed by the top and bottom portions of said endless sheet or belt, and said'eggs will rest on the bottom portion of said sheet or belt'and the top portion 1 thereof will rest on sai'deggs, and when the rollers 03 and d are turned the eggs willalso be turned withoutchangingthe relative po, sitions in the tray or holder. It will thus be seen that the said eggsmay be turned in either direction and'to any extent whenever desired simply by manipulating one or both of the rollers cl and d by means ot-the han--' dles of the pins g, and in this operation and,-

at all times theegg holder or carrier is" maintained in a horizontal position bythe roller 6. The roller 0, however, is not ab solutely essential, but is preferably employed in incubators where the egg holder is of considerable dimensions longitudinally of the incubator.

It will also be understood that my improved egg turner and holder may be made of any desired dimensions according to the dimensions of the incubator in which it is to be used, and changes in and modifications of the construction herein described may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. An egg holder and turner for incubators, comprising a frame, rollers mounted in connection therewith, and an endless openwork sheet passed around said rollers and between the top and bottom parts of which the eggs are placed, the dimensions and construction being such that the eggs rest 011 the bottom part of said sheet, while the top part thereof rests on the eggs.

2. An egg holder and turner for incubators, comprising a frame, rollers mounted in connection therewith, and an endless sheet of wire mesh mounted on said rollers and between the top and bottom parts of which the eggs are adapted to be placed, the dimensions and construction being such that when the eggs are placed in position they will rest 011 the'bottom part of said sheet, while the top part thereof will rest on said eggs.

In testimony that I claim the foregoing as 1 my invention I have signed my name in presence of the subscribing witnesses this 24th day of August 1911.
